LS200
Liquid Level Switches with 2” NPT mounting are
float activated to operate an electrical SPDT snap switch
(optional DPDT on LS200 models) for alarm or shutdown of
an engine or electric motor. The LS200 screws directly into
the vessel wall and can be used with a weld collar or external
float chamber. L1100 models (1-1/2” NPT) are available.
LS200NDVOR
is a float-activated,
pneumatic-vent level device used to
operate dump valves or similar devices.
The LS200NDVOR provides a 2” NPT
mounting with a pneumatic snap action
output for interfacing with pneumatic
devices such as our DVU scrubber
dump valve or with other pneumatic
instrumentation. This unit is supplied
with a pr
essure filter regulator and
Murphy pressure gage which are
recommended for improved system life
and trouble-free operation.
LS200NDVO
Pneumatic level switch with snap action
Dump Valve Operator (DVO) without the
Pressure Regulator for those applications
where the system provides a filter regulator
for “instrument quality” air or gas as the
control medium.
LS200N
Pneumatic level switch without the DVO
and filter regulator.

Two piece union design with manual valve operator
allows soft plug and hard seat to be replaced
without
disassembling outlet piping or scrubber
pipe
connection. Diaphragm actuated valves
operate on 30-70 psi (207-483 kPa; 2-5 bar).

High Level Shutdown Switch
Stainless steel float actuated level switches to alarm
and/or shutdown the equipment.

The Murphy Gas Compressor Scrubber Level System (SLS)
The system provides for
liquid control in gas scrubber
applications, by dumping
liquids to drain and protecting
compressors with a high
liquid level switch. Wetted
metal parts are made to
survive constant use in
corrosive environments.
See Bulletin: SLS-04005B for
more details.
